For a system corresponding mainly to a uniform electric field, the flashover voltage is slightly lower than the breakdown voltage of air alone, for the same electrode gaps. The decrease in the flashover voltage is due to the presence of small air pockets between the electrodes and solid dielectric, the influence of moisture and the non-uniformity of the electric field resulting of the difference between the permittivity of both the solid and that of air. The non-uniformity of electric field increases with the voltage because of the surface charging that takes place in this situation.

The Laplace transform proves to be a highly valuable tool in electronic circuits analysis.

Write the Verilog code for a 12-bit shift register with ability to shift left or right, synchronized parallel load, asynchronous reset, and serial output? The register is able to load the 12-bit input value (at the positive edge of the clock) if the load signal is one, shift the value in register one bit to the right (at the positive edge of the clock) if the rss signal is one, shift the value in register one bit to the left(at the positive edge of the clock) if lss signal is one, and reset the value in the register at any time if the rst signal is one. The shift register has two 1-bit output which are the MSB (Most significant bit) and LSB (Least significant bit) of the register at any given time. The priority of the signals is in the order as follows with rst having the highest priority. rst, load, rss, lss. When shift register is shifting the value to the right, the MSB bit takes in the load input MSB bit. When shift register is shifting the value to the left, the LSB bit takes in the load input LSB bit.

ASSIGNMENT: A CRITIQUE OF THE DELIVERY OF HOLISTIC SUSTAINABILITY IN ELECTRICAL SYSTEM DESIGN

PLEASE note a key phrase in the brief is: It is important that the student takes the perspective of their prospective profession in this assignment. They should consider to what extent their chosen profession can or cannot influence the delivery of holistic sustainable solutions. Some aspects may be beyond the profession’s control, others within its sphere of influence. The barriers to delivery of holistic sustainability solution in your prospective profession should be discussed and where possible, enabling factors that would enable increased delivery of sustainable solutions should be debated. Students are also required to discuss how they can incorporate Design for Sustainability methods with any engineering formal design process.

Part 1

Systems engineering is said to be a disciplined process. Why do system failures still occur? Choose an example of a technology or system failure (Examples: early airbags, Titanic, Challenger or Columbia disasters). Then respond to the following in discussion:

Explain reasons for the failure. Use figures and/or other visual aids to explain your answer.

Identify and explain any system acquisition processes that were not followed that may have contributed to the failure.

You may also use your own relevant experience.

Assume you are making a compisite material airplane, which has ligter weight and more fuel effciency. Describe how your airplane will put pressure on a culture outside of America (Choose a specific country). How your airplane will affect their society, culture, economic, and envornment, etc?  

Consider an RC circuit with resistance R and capacitance C. The circuit is stimulated with a pulse of amplitude A and width T.

The purpose of this study is to understand what happens to the impulse response, capacitor voltage, and resistor voltage for various resistor values: 600 ?, 1000 ?, and 1200 ?. The name of the MATLAB script will be called project2a. Excite the circuit with a rectangular pulse voltage of amplitude=5 V and pulse width of 10 ms. Plot the results of each resistor value from t=0 to t=20 ms on the same graph (3 graphs-impulse response, capacitor voltage, and resistor voltage). Label all axes, put a grid on the graph, and apply the proper legend. Comment on and explain the results.

For all cases of the study, the capacitor will have a value of 1 µF. Use the function below to make graphs.

function [ Vc Vr t ] = rc_voltages( A,R,C,T,Tend )

t=0:0.0001:Tend;

for i=1:length(t)

if t(i)

Vc(i)=A*(1-exp(-t(i)/(R*C)));

Vr(i)=A*exp(-t(i)/(R*C));

else

Vc(i)=A*(exp(T/(R*C))-1)*exp(-t(i)/(R*C));

Vr(i)=A*(1-exp(T/(R*C)))*exp(-t(i)/(R*C));

end

end
